Just be around him. People in situations like that need company. Don't try to overcompensate. Cracking jokes as soon as you walk through the door doesn't change the reality of the scenario. Be a friend. Ask him if there's anything you can do. Does he need anything from the store? Stuff like that.
Good luck with it man.
